Claude publishes a live progress page for long tasks: steps, a segmented progress bar, time elapsed and an ETA that learns from real timings.

how-long: Live Progress Bar & ETA
Example session with this skill installed
Go through the 12 CSV files in ./sales-2025: clean them, compute the quarterly metrics, draw the charts and write up the Q3 report. It'll take a while, so show me a progress bar and how long it will take.
- Read your context and instructions
- Compiled the how-long
- Generated the document
Summary
Live progress is on. I published a page called
"Q3 report progress": open its card in this conversation at any time to see what I'm doing and how long is left. I update it at every step.
The progress page, 25 minutes in
| # | Step | Status | Time | Estimate |
|---|---|---|---|---|
| 1 | Read and check 12 data files | Done (2 files were GBK-encoded, converted) | 4 min | 3 min |
| 2 | Clean the data | Running, 7 / 12 files | 21 min | 8 min |
| 3 | Compute quarterly metrics | Pending | 5 min | |
| 4 | Draw charts | Pending | 6 min | |
| 5 | Write the report | Pending | 10 min | |
| 6 | Export PDF | Skipped: switched to a Docs document | 2 min |
Time left: 56 min ·
Expected to finish: 17:01 ·
Progress: 24% ·
Pace: 2.2× the estimated time ·
Estimate quality: Fair
Activity
- Task started
- 2 files had the wrong encoding, converted to UTF-8 (warning)
- Step 1 done, cleaning started
When it finishes
The page switches to
Done, shows the total time and a one-line result, for example: "Report done: 18 pages with 6 charts. Q3 revenue up 12% on Q2." If your agent supports push notifications, you get one as well.
Next steps
- Keep working on something else: the page updates by itself
- Ask "how long is left?" at any time, or just open the card
- Say "no progress page" to turn it off for the rest of the conversation

About this skill
Long agent tasks are a black box: you can't tell how far along Claude is or how much longer it will take. how-long fixes that. At the start of a long task, Claude publishes a live progress page you can open at any time.
What you see
- What Claude is doing right now
- Every step, with its status and time taken
- A segmented progress bar, each segment sized by that step's estimated time
- Time elapsed, time left and the expected finish time
- Whether the work is running faster or slower than estimated ("20% slower than estimated")
- A short activity log
The page updates live, with no refresh. It follows your language (English or Chinese) and your light or dark theme.
When it kicks in
- Tasks Claude expects to take about 10 minutes or more, or with 6 or more steps
- Whenever you ask for a progress bar, progress updates, an ETA or "how long"
- Say "no progress page" and it stays off for the rest of the conversation
How the ETA works
Claude estimates each step when it plans the task. The page learns a pace from real timings (actual time compared with the estimates, smoothed so one early outlier doesn't swing it), uses the measured rate for steps like "7 / 12 files", and leaves time spent waiting for your reply out of the estimate. If updates stop for a long time, the page says the task may have stopped instead of claiming it is still running.
Built for long runs
Claude saves the page address in progress-state.json, so if its context is compacted halfway through, it finds the page again and keeps updating it.
Requirements
The live page uses Claude's artifacts with a database (the Artifact and ArtifactData tools): the Claude app and Claude Code sessions that have artifacts. In agents without them, the skill falls back to the agent's own task list or a checklist, so you still get step tracking, but no live page or ETA.
